Every Economics IGCSE past paper in the collection that assesses the mixed economy.
These papers were matched to the mixed economy automatically, by keyword patterns in their questions and mark schemes. A hand-check of 100 randomly chosen matches, each read against the source question paper and the specification's own statements for the topic, found 99 that genuinely assess the topic and 1 that does not — 99% (95% confidence interval 94.6–99.8%). That is a good way to find practice on a topic, not proof a paper covers it, and a paper missing from this list may still assess it. The topics are the specification’s headings, which are broad: one question on any statement under a heading was enough.
